Dietary factors related to liver xanthine oxidase.
In a previous study (1) it was shown that dogs maintained on a purified diet developed a defect in acetaldehyde metabolism. Of the five known enzyme systems that could theoretically be involved in acetaldehyde metabolism in viva (aldolase, mutase, carboxylase, aldehyde ox&se, and xanthine oxidase), the xanthine and aldehyde oxidases seemed most likely to be dependent upon a dietary factor not a...

متن کاملA bioassay procedure for the dietary factor related to xanthine oxidase.
Previous studies (l-4) have shown that the level of xanthine oxidase in the liver and intestine reflected the dietary intake of some unidentified factor,l provided the protein content of the diet was adequate. Changes in the liver enzyme could not be adapted into a good bioassay procedure because the effect of liver residue factor1 was relatively small and because dietary protein rather than LR...
متن کاملFurther studies with xanthine oxidase inhibitors.
The osidase and dehydrogenase activities in the enzymes oxidizing xanthine can be differentiated by the use of certain inhibitors (1). The present study was designed to see if such inhibitors are specific for the reaction with oxygen, or whether these agents also block the transfer of electrons to cytochrome c and nitrate. Both reduced diphosphopyridine nucleotide and hypoxanthine were studied ...
متن کاملRecent mechanistic studies of xanthine oxidase.
Introduction The molybdenum-containing hydroxylases constitute one of the three major categories of mononuclear molybdenum enzymes. In comparison with other biological hydroxylation systems they are unique in that they utilize water rather than dioxygen as the ultimate source of the oxygen atom incorporated into product, and generate rather than consume reducing equivalents in the course of tur...
